Mallory 29209 Comp Pump Series 140

The Mallory Fuel 140 Electric Fuel Pump is a high volume high pressure fuel pump designed for high performance street, racing and marine applications. The operating fuel pressure is factory set at 12 PSI. This pump must be used with a fuel pressure regulator to prevent carburetor flooding. We recommend a 3/8" or larger fuel line with this fuel system. The Mallory Fuel Series 140 Part Nos. 4142 and 4142A come with a 3 Port Return Style Regulator. These fuel systems must have a fuel return line installed between the fuel pressure regulator's fuel return port and the fuel tank.
